Kansas, have invented new and usetul ln1- 1 provements in Heaters, of which the follow.

ing is a specification.-

This invention relates to improvements in heaters, moreparticularly the fluid-fuel or gas-burning type.

The invention has tor its object to provide tor readilyefi'ecting the heating action.

A. further object is to provide for producing a pro-lighting action in connection with the primar burner.

a A still rther object is to provide tor spreading the ignited fuel or flame within the heater.

A still further object tocarry out the aforesaid ends in an inexpensive, expeditious and eflective manner.

V The invention consists of certain instrumentalities and dentures substantially as hereinafter tully disclosed and defined by the claims.

In the accompanyingdrawing, illustrating the preferred embodiment of my invention wherein it will be understood that various changes and modifications may be made aato the detailed construction and arrangement ot the parts, without departing from the spirit thereol, Figure l is a sectional elevation oi" the heater. Fig. 2 is an en larged vertical longitudinal section of the pilot-light controlling valve. Fig. 3 is a sectional view taken on line yy of Fig. 2. Fig. 4c is a transverse sectional view, showing a modification ot the pilot-light control ling valve. Fig. 5 is a like view, showing a second modification of the pilot-light controlling valve. I

In carrying out my invention, l provide a casing or drum 1 preferably at sheetmetal,

nary type. The casing or which issupported upon les 2 of any ordi; drum 1 is prefer ably bottomless, and has arranged therein near its upper or outlet end, a diaphragm till or deflector 8, for spreading the flame and throwing it toward the sides of the drum the diaphragm or deflector being supported by means ol brackets a secured to the inside". 'ot the casing or drum and to the dlaphragni or deflector, a narrow annular space or passage 5 beinglett between the periphery. ot the deflector and the drum, for the upward passage of the ignited gas or flame, and a flame toward the sides of the casing or drum. This throwing of the gas-flame laterally within the drum or casing 1 has the efl'ect of more fully utilizing the gas or fuelflame and accordingly augmenting the heating action of the drum.

Supported within the casing or drum 1, below the lower diaphrag' a or deflector 'l' is a burner 10, preferabl of the ordina star type, the same including a heamember 11 and radial tubular arms or jetpipes 12 delivering upwardly against the in tial or primary deflector dr diaphragm 7. ln suitably supporting the burner 10 in position, the supply-pipe l3 therefor, which enters the drum '1 centrally through its lower end, is u held by means of a bracket 14, projecting rom the inside of the drum, said supply-pipe extending downwardly and laterally below the bottom edge of the drum, and having connected thereto a valve or cook 15 supported in a leg 2 of the drum.

an imperforate plate, shield or guard l5 is supported upon the legs 2 of the casing or registration with the nozzle 19. The oppo- 7 siteend ot the valve casing 17 has suita ly attached thereto a plate or closure 21 and through a central orifice in the closure or .j'plate extends the handwheel stem 22 ot the valve or plug 16, the handwheel being desig nated by the numeral 23, the plug or valve being opened and closed simply by rotation and not by endwise movement.

lhe plug or valve 16 and its casing or in for ltltll ltlli llO closure 17 are provided'with arcuate grooves or passages or by-passes, 24 and 25, respectively, which are adapted for maximum communication one with the other only when the port 16 of the plug or valve is wholly-out of communication or register with the nozzle 19. The valve-casing groove or passage 25 has at one end a right-angled arm. or extension 26 adapted to communicate with the intake nozzle 19, the casing being also provided with an upwardly inclined passage or jet opening 27 communicating with the' groove 24 and adapted to deliver a pilot-flame for igniting the gas issuing from said primary burner 10.

It will be observed that b rotating the plug or valve 16 so as to e ect connection between the by-passes 24 and 25, the port 16 will not register with the gas-intake nozzle 19. The gas, however, will escape through the grooves 24 and 25 into the jetopening 27, and when ignited at the mouth of the jet opening, a flame will be thrown upon the primary burner 10. By rotating the plug or valve 16 further and in the same direction, registration is efiected between the port '16 and the gas-intake nozzle 19; connection, however, between the by-passes 24 and 25 at this juncture is severed, and

the gas-flame at the mouth of the jet-opening 27 is extinguished. Before the pilotflame is put out, however, a quantity of gas will; have passed through the primary burner 10 andwill have-been ignited by the pilot-flame.

In Fig. 4, 'there is shown a casing 17 "having a channel 25, communicating with the jet-passage 27, the plug 16 havinga channel 24 communicating with the extension-passage 26 in the casing 17, the arrangement of channels or passages in the plug and in the casing being interchanged, as compared with Fig. 3.

As disclosed in Fig. 5, the plug or valve 16 is provided with a superficial groove or by-pass 24 which is adapted to establish direct communication between the orts 27 and 19, when the valve is rotated. It is ap parent that, when the valve 16 is adjuste as indicated in Fig. 5, there will be no gassupply to the primary burner 10. By adjusting or turning the valve 16 so as to'es' tablish communication between the ports 19 and 27 through the by-pass 24", a pre-lighting gas-su ply will be delivered through the port 2 toward and upon the primary burner 10. By continuing to turn the valve 16 in the same direction, to the left, the port 16 will be caused to register with the by-pass 19, while the port 24 will still be.

in communication with the port 27, the ports 19 and 16 eflecting a gas-supply to the valve. 16 and, therethrough, to theprimary burner 10, which gas-supply. will become ignited from the pre-lighter or pilot flame. By continuing to turn the valve'16 in the same direction, the by-pass 24 will be moved out of registration with the port 19 and accordingly out 01f the gas-supply at that point, the operation resulting in extinguishing the pre-lighter or pilot flame and yet allowing the primary burner gas-supply to remain intact. By reversing the rotatlon of the valve 16, the primary burner gas-supply will be cut off and its flame become extinguished, but not, however, before coinmunication has again become established between the port 27 and the by-pass24", thus providing for re-lighting the pilotflame previous to extinguishing the primary burner flame.

What is claimed is 1. In a device oi the class described, a casinghaving .an inlet, the casing being provided with an inclined jet opening disposed at an acute angle to the axis ofthe casing; a hollow valve journaled in the casing and closed at one end, the open end of the valve dischargingthrough one end of thecasing, the valve having an inlet adapted to be brought into and out of registration with the inlet of the casing; the valve and the casing having cooperating grooves establishing communication between the jet opening and the inlet of the casing when the inlets are out of alinement; and a burner supported above the discharge end ofthe jet opening. v

2. In a device of the class described, a casg having an inlet; a pipe projecting from me end of the casing; a burner supported by the pipe; there being a jet opening in the casing above the pipe, the opening being upwardly inclined'toward the periphery of the burner; a hollow valve journaled in the casing, the valve discharging at one end into the pipe, the valve having an inlet adapted to move into and out of registrationwith the inletof the casing; the-valve and the "casing having coiiperating grooves estab- 'lishing communication between the jet opening and the inlet of the casing whenthe inlets are out of alinement.

In testimon that I claim the foregoing as my own, I ave hereto aflixed my signa- .ture in the presence of two witnesses.
